(Tips: bring your own water bottle, dress in layers, Mark does accept Apple pay/cc/etc. with the option of emailing/printing the receipt to you. Fast process.)
Absolutely wonderful experience with Mark. He was FRIENDLY and accommodating on a cold Monday morning! He guided me in with directions and was quick with texts and calls. He was very patient and kind. I rented a road bike to ride from Sausalito, across the GG bridge and into the presidio. Mark recommended the trails with the best views for the ride, local coffee shops and was genuinely interested in my journey and where I was from. He was also concerned if I had enough layers on for the cold morning. He hooked me up with a discount to the awesome Italian restaurant next door which had THE BEST smoked salmon and capers dish (very reasonably priced, a kind manager and staff and quaint waterfront location). After the ride, the return process was simple and fast. The entire morning was a WIN thanks to Mark. Good vibes!
Mark gave us some sweet bikes to take up Mt. Tam. He was super knowledgeable about the area and very friendly.
Definitely will return next time I could use a rental so I can see his historic gallery again! Amazing experience.
